The John Marshall Ju/'hoan Bushman Film and Video Collection contains full film and video projects (outtake material), film production elements and edited films and videos, audio tapes, still photographs, negatives, transparencies, slides, published and unpublished writing by John Marshall and others, study guides for edited films, Nyae Nyae Development Foundation and Advocacy files, maps, and production files that include letters, shot logs, translations, transcriptions, editing logs, treatments, and proposals spanning from 1950-2000. This material comprises Marshall's long-term documentary record of the Ju/'hoansi of the Nyae Nyae region of the Kalahari Desert in northeastern Namibia. A great deal of the film and video footage focuses on one particular extended family, that of Toma Tsamko, whose ancestral home is at /Gautcha, an area with a large salt pan and a permanent waterhole. The life stories of some family members are captured in the footage; appearing as children in the 1950's, middle-aged parents in the 1980's, and pensioners in the final years of visual documentation. The Marshall Collection also documents other Ju/'hoansi living in Nyae Nyae and elsewhere, their relationships with neighboring ethnic groups, and national politics that affected Ju/'hoansi. Marshall also documented the local political body (the Nyae Nyae Farmers' Cooperative, or NNFC), the foundation he started (the Nyae Nyae Development Foundation of Namibia, or NNDFN), and the ways in which both groups worked with and were affected by international development organizations and foreign aid during the 1990's.
